CRASH INJURY PREDICTION MODEL

Automobile crash injury was analyzed using data from the Crash Performance Injury Report (CPIR) for crashes which occurred since 1 January 1970 involving 1969 or newer cars, vans and pickup trucks. An injury prediction model was developed using delta V, vehicle weight, occupant age, seating position, crash configuration, and restraint usage to predict expected AIS. Expected AIS was then used to estimate the probability of death and severe injury. The model estimates were found to approximate the observed probability of death and severe injury from the National Crash Severity Study (NCSS) data file. (a) (TRRL)
